/** @file lib/stdint.h
 *
 *  @brief Standard integer type definitions
 *
 *  @bug The standard integer state of our library is a little questionable.
 *  I think types.h has become a dumping ground for things that don't fit well,
 *  and some of that should move here/be deleted.
 *  It's missing a few things that it probably should have (wchar, ptrdiff
 *  sizing), but I think it should be fine until students actually use those
 *  features.
